During the March 2025 Fram2 polar mission, an all-civilian crew successfully captured the first diagnostic X-ray images in space using a portable, commercial off-the-shelf system. The experiment demonstrated that non-medical personnel, with just four hours of training, can generate medical-grade radiographs in microgravity, a key requirement for future long-duration missions to the Moon and Mars.
The Fram2 Mission and the Move Toward Orbital Imaging
On March 31, 2025, the Fram2 mission launched aboard a SpaceX Crew Dragon, marking the first human spaceflight to traverse a 90-degree polar orbit. While the mission was notable for its unique trajectory, it also carried a compact, wireless MinXray Impact system intended to solve a long-standing gap in space medicine: the lack of diagnostic radiography.
For decades, astronauts on the International Space Station have relied primarily on ultrasound technology for medical diagnostics. While effective for some applications, ultrasound requires specialized training and a transmission medium, limiting its utility in harsh, remote environments. As Dr. Sheyna Gifford, a Mayo Clinic aerospace-medicine physician and lead author of the study, noted, It’s been a dream for aerospace medicine to have more than one imaging modality for diagnosing illnesses and injuries in space.
Training Non-Experts for Space-Based Diagnostics
The success of the Fram2 experiment hinged on whether a portable device could be operated by crew members who were not medical professionals. The crew included a cryptocurrency investor, a filmmaker, an engineer, and a polar explorer—none of whom were physicians.
The results, published in the journal Radiology, confirmed the feasibility of this approach. Independent radiologists who evaluated the images found that they were of diagnostic quality, comparable to preflight scans taken on Earth.
“Acquiring a diagnostically useful X-rays in space is something that anyone can do. Three very talented nonmedical people with four hours of training in one of the harshest environments did it right and did it well.”

The crew successfully imaged their own hands, forearms, chests, abdomens, and pelvises.
Beyond Crew Health: Inspecting Mission Hardware
The utility of an X-ray system in orbit extends well beyond human medical care. Because deep-space missions will operate far from the immediate medical evacuation capabilities of Earth, crews will need to maintain their own safety and equipment integrity.
This capability is vital for long-term lunar or Martian surface operations, where taking equipment apart for inspection is often impossible.
“For sustained human presence in space, X-rays are critical not just for crew members but also for other mission components like electronics and spacesuits. The only way to look inside these objects without taking them apart is to X-ray them.”

Implications for Future Deep-Space Missions
The need for autonomous diagnostic tools has grown more urgent as agencies look toward the Moon and Mars. Recent events have underscored the risks of operating in space without Earth-based diagnostic support. In January 2025, NASA cut short the Crew-11 mission on the International Space Station after a crew member developed an apparently serious
medical condition.
For a mission to Mars, an early return is not an option. The Fram2 results prove that portable radiography can bridge this gap. The device returned to Earth on April 4, 2025, with only superficial damage to its housing, confirming that the hardware is robust enough for spaceflight operations.
